why

why is there only two members of the sith instead of building up like a sith army wouldnt that be easier other than the whole fact of apprentaces killing there masters

because of all the in-fighting. their main goal is power, and they'd all kill each other while vying for that power.

Because the sith are so evil that they inherently kill one another for power. Darth vader tried to do that with luke, as Palpy did with Dooku.

Palpatine- "Those who gain power, are afraid to loose it."

Once again Lord Yoda has a point or agood quot point post whatever.

But yeah the Siths don't share power or have equal share of it the Jedis get power but can only gain more by training and learning from other Jedi but they don't kill each other cuz they need to learn from each other.

The Jedi are more of a team the Siths just like to kill compotition and are more do it my self solo kinda thing. 😛
